Event Description
Introduction to Spark
Presented by Carol McDonald, MapR Technologies
Apache Spark is a fast and general engine for large-scale data processing. In contrast to Hadoop's two-stage disk-based MapReduce paradigm, Spark's in-memory primitives provide performance up to 100 times faster for certain applications.
The Spark software stack includes a core data-proccessing engine, an interface for interactive querying, Sparkstreaming for streaming data analysis, and growing libraries for machine-learning and graph analysis. Spark is quickly establishing itself as a leading environment for doing fast, iterative in-memory and streaming analysis.
This talk will give an introduction the Spark stack, explain how Spark has lighting fast results, and how it complements Apache Hadoop.

OpenAI Releases GPT-6 Astra for Coding and Computer Use
OpenAI has released GPT-6 Astra, a new model focused on coding, computer use, long-running agentic tasks, and cybersecurity, with availability across ChatGPT, Codex, and the OpenAI API.
By Daniel DominguezBeyond Autonomous Teams in Software Product Development
Autonomous teams are an article of faith in modern software development. The shape of our value determines what we can do; it determines our trade-offs between agency and coherence. We all have a purpose, and we all have agency to do something, hence the suggestion is moving from product focus to value center thinking.
By Ben LindersPresentation: Accelerating Performance by Incrementally Integrating Rust Into Existing Codebase
Lily Mara explains how to avoid high-risk software rewrites through incremental FFI refactoring. She shares how engineering teams can replace Python bottlenecks with Rust via PyO3, demonstrating how to achieve dramatic function-level speedups, seamless integration testing, and meaningful infrastructure cost savings without microservice overhead.
By Lily MaraArticle: When Spec-Driven Development Pays Off
AI coding assistants have become a core part of software development. AI-generated code has shown productivity gains, but it's also contributing to security weaknesses and familiar bug patterns. In this article, author Nitin Garg highlights the bottleneck has moved from code generation to code verification, and how to detect & mitigate it when the AI-generated behavior diverges from the intent.
By Nitin GargIETF Publishes RFC 10008, Adding the QUERY Method for Safe Requests With a Body
In June 2026, the IETF published RFC 10008, introducing the QUERY method to HTTP, the first new standard HTTP verb since 2010. QUERY enables developers to send richer query filters in the request body while maintaining cacheable, safe, and idempotent semantics. This addition addresses long-standing limitations with GET and POST methods, facilitating improved API interactions.
